vm2: NodeVM builtin allowlist bypass via node:test.run() execArgv allows sandbox escape

Summary On Node.js 24 and newer, vm2 can expose the host node:test module to sandboxed NodeVM code when the embedder explicitly allows the node:test builtin. Sandbox code can reach that module through require'node:node:test' and call run with attacker-controlled execArgv. node:test.run starts a...
